It seems that this is what I’m reading about the two if I’m correct.
Thanks that’s one step closer to helping me fix this nightmare off a computer..
Oh and if you know this then please check out my other related questions. Thanks!

64 bit processor can be operated with 32 bit OS also. I am having 64 bit processor but still my OS is Windows XP 32 bit Edition.
If you go for 32 bit OS for 64-bit processor you can’t get the real benefit of the 64-bit processor.
A 32-bit OS is not capable of using all instruction set of the 64-bit processor. Some instruction set which is exclusively for 64-bit arithmetic can’t use by the 32-bit OS as it is designed to drive a 32-bit OS. Still u can use other instruction which doesn’t need 64-bit operation. So if u use 64 bit OS for 64 bit processor, roughly you can improve your system performance by two fold. But this is not true always
64-bit OS always needs a 64-bit processor to run.
64-bit processor are developed in such a way that it can operate only on 64-bit processor. Design of such 64-bit OS is exclusively for 64-bit processor architecture. Thus 64-OS doesn’t fit on 32-bit processor as processor not able to compute 64-bit instruction which is generated by a 64-bit OS.
I’m a bit confused about this. I always thought you’d have to have at least a CPU that was a «64 bit» cpu, and probably a motherboard that could handle 64 bit memory addressing.
But recently I was checking out some info about my home PC processor (Q6600) and was surprised to find out that it can handle 64bit operating systems, even though it wasn’t advertised as such. I’ve also seen sites claiming that any core 2 CPU from intel can do 64bit, which I find it hard to believe.
So, can I slap a 64bit OS on any Core 2 machine? Does the motherboard also come into play?

The only technical requirement to be able to install a 64bit version of an OS is that the CPU supports 64bit extentions. Most CPU’s by AMD and Intel in the last couple years have included the 64bit extentions (AMD64/EM64T)
Your motherboard would most likely not prevent you from installing a 64bit OS, but you may not be able to go beyond 4gb of RAM depending on what the motherboard supports.
Some helpful questions:
Removed my previous answer because it is just the same as other answers. Added another requirement.
One of the most critical requirement for running a 64-bit OS is not just hardware, but the user too :
- User swears never to install anyhow drivers which might be 32-bit on a 64-bit OS.
- User must understand that just because 64-bit is two times of 32-bit, doesn’t mean the system will go twice as fast.
- User must not use the «I run a 64-bit OS» as a bragging right to others so the Net will be spared the nightmare of answering «Why is my 64-bit OS crashing/slower/not-twice-as-fast/».
- User must not be confused as to whether he can run 64-bit or not. If he’s confused, then he’s not ready for 64-bit.
Cheers. Stay on the x32 bandwagon — it still performs very well, and there are only marginal benefits to move on to x64 — the chief benefit being you can run more than 4GB (or 3.2, or 3, or whatever) of RAM.

Hi, I just purchased an HP Envy dv7-733cl notebook pc. I do not know a whole lot about operating systems etc.. and I have a few questions. The specs on the computer say it has an AMD quad core A10-46000M accelerated processor, 1 TB hard dirve and 8192 MB DDR3 SDRAM (8GB). I have not opened it yet because the packaging states that «This system requires a separately purchased 64 bit operating system and 64 bit software products to take advantage of the 64 bit processing capabilities of AMD technology.»
1) Does this mean it does not have the quad core capability without it?
2) I beleive from HP website that it comes with Windows 8 64 bit version, does this have nothing to do with the 64 bit processor they are talking about?
3) What will I be missing out on without the 64 bit processor?
4) I mainly use my computer to surf net, make cds, make simple home movies, do stuff with pictures — is not having this going to be a big deal?
5) how can I purchase the 64 bit operating system and about how much will it cost and can i install it myself?
